Convert EPS to JPG + Drupal

[kumkum]

Hello,

I use IM on my Drupal site. IM created many jpg thumbnails from following image formats: tiff, jpeg, gif, png. But IM does not create jpg thumbnails for eps images. I can not find the answer to this problem on the Drupal forums.
Should I install an additional module to generate jpg or png from eps file? Is there a code to be inserted in the convert function?

Thank you for your help.

What error message do you get? I think IM delegates that conversion to ghostscript.
